The commonest Norwegian verbs do not take -et or -te. Er becomes var, har becomes hadde, går becomes gikk, kommer becomes kom, får becomes fikk, ser becomes så. For ago, the time comes first and siden after it: for to dager siden.
Examples
- I går var jeg i Trondheim.
- Yesterday I was in Trondheim.
- For to dager siden ringte jeg henne.
- Two days ago I called her.
- Forrige uke fikk vi et brev.
- Last week we got a letter.
The mistake to avoid
The frame is for ... siden and both halves are needed.
Where this fits in
Talking about the past, Norwegian A2: Tell stories about yesterday, last weekend, and life experiences using preteritum (simple past).
